We are pleased to announce that planning is taking place for the 10th Trinity Triathlon.

Named British Triathlon Children’s Event of the Year (2016) and London Region Children’s Event of the Year on three occasions, the event is open to boys and girls aged 6 to 19.

From elite athletes, many in the GB squad, to first-time triathletes our Trinity Triathlon is enjoyed by all. With excellent pre-race information and marshalling available on race day, competitors can enjoy a fantastic day!

Entries will open early in 2021 and further detail can be seen on the British Triathlon events web site:

The Coronavirus outbreak resulted in the cancellation of all events in 2020 but we are hopeful that conditions will allow the race to take place in 2021. If cancellation has to occur again, we guarantee full refunds to all competitors.
